At Ayr Sheriff Court this week, Mr Robson explained to Sheriff Scott Pattison that it was impossible to take instructions from his client.

Just two weeks ago, Simpson, 37, appeared in the dock and shouted at the Sheriff that a seagull was loose in the court and a baby was to be born in Cornton Vale.

Simpson then shouted abuse at her lawyer before she started singing Puff The Magic Dragon as loud as she could.

Despite her erratic behaviour, Dr Scott and Dr Johnstone have not been forthcoming with the psychiatric reports that the court has asked for.

Depute fiscal Claire Smith told the court that she had received a letter from Dr Scott saying she has “gone as far as she can” with Simpson.

Mr Robson told the court: “I believe this is part of an agenda. They don’t want her under the care of Ailsa.

“She has a personality disorder – that takes a lot of time, effort and money to manage.”

Dr Johnstone has intimated that he does not feel there is any need for reassessment of Simpson’s mental state – even though he has not seen her for a year.

Sheriff Pattison decided to get reports from psychiatrists outwith Ayrshire, who have never dealt with the Tarbolton woman before.

Reports from the doctors at Carstairs and Douglas Inch Hospital in Glasgow are expected by Friday.

By that time Simpson will have served the equivalent of a two and a half month prison sentence for allegedly going into Ayr police office on March 18 last year and causing fear and alarm by shouting and swearing.

Mr Robson applied for bail on behalf of Simpson, but it was refused.

Dr John Taylor, associate medical director of mental health services in Ayrshire and Arran, said: “Our clinical staff provide reports to courts using their professional and clinical expertise.

“Our clinical diagnosis is based on our assessments of individual patients and while we accept that courts can either accept or reject our clinical opinion we would reject any allegation of clinical staff having an agenda.

“It would be inappropriate for us to comment on an individual patient due to patient confidentiality.”
